The results provide evidence that when there was an increase in the sodium chloride concentration the mass of the potato prisms declined. At the zero percent concentration there was an increase of mass by 1.75%‚ from there the 1%‚ 3%‚ 5% and 10% begun on a downward trend with the percentage change in mass declining. The graph was on a steady decline from 0% being the highest point with a change of mass of 1.75% finishing with the 10% solution on a decline of -12.28%. From observing the scatter plot

into 1 cm cubes. 3) A 1 cm cube of liver was placed inside a 250mL measuring burette‚ we then added 9mL of a select concentrate of hydrogen peroxide and using the teat pipette we then added 1 mL of detergent and a drop of water. The timer was started. 4) The timer was stopped after two minutes had passed and then the results of how many mL of foam were produced were taken down. 10 mL was subtracted from the end result due to the initial mL of the starting materials added. 5) Steps 1 – 4 were repeated

LCD based voting machine using 8051 microcontroller Electronic voting machine has now replaced the traditional mechanism of voting due to several advantages like security‚ automatic counting etc. This project presents a way to develop an electronic voting machine which displays the count of votes on a 16x2 LCD interface. A user can get his/her vote register through a set of switches (one for each candidate). After every cast of vote‚ the subsequent count can be seen on LCD. The circuit uses AT89C51

into the man‚ which he has aspired to be. Naturalism is very evident in London’s “To Build a Fire”. The entire story happens in the everlasting realm of nature. The man is traveling through the frozen land and does not take the advice of an “old-timer”. Nature has no concern for the man or his well-being. Elements of naturalism are evident from the first lines of the story. “Day had broken cold and gray‚ exceedingly cold and gray”‚ the narrator begins the story showing how unpleasant nature can

widely used 8-bit microcontrollers in the world. In this book the authors use a step-by-step and systematic approach to show the programming of the AVR chip. Examples in both Assembly language and C show how to program many of the AVR features‚ such as timers‚ serial communication‚ ADC‚ SPI‚ I2C‚ and PWM. The text is organized into two parts: 1. The first seven chapters use Assembly language programming to examine the internal architecture of the AVR. 2. Chapters 7-18 use both Assembly and C
